DescriptionIntel 82527 Serial Communications ControllerThe 82527 serial communications controller is a highly integrated device that performs serial communication according to the CAN protocol. The CAN protocol uses a multi-master (contention based) bus configuration for the transfer of "communication objects" between nodes of the network. This multi-master bus is also referred to as CSMA/CR or Carrier Sense, Multiple Access, with Collision Resolution. The 82527 performs all serial communication functions such as transmission and reception of messages, message filtering, transmit search, and interrupt search with minimal interaction from the host microcontroller, or CPU.The 82527 is Intel’s first device to support the standard and extended message frames in CAN Specification 2.0 part B. It has the capability to transmit, receive, and perform message filtering on extended message frames with a 29-bit message identifier. Due to the backwardly compatible nature of CAN Specification 2.0, the 82527 also fully supports the standard message frames in CAN Specification 2.0 part A.
